The DSC1123AE2-200.0000 is a 200 MHz MEMS-based XO (Standard) from Microchip's DSC1123 series, delivering an LVDS output with ±25 ppm frequency stability across its -20°C to +70°C operating range.
Supply voltage range and output type
Supply voltage spans 2.25V to 3.63V, covering common 2.5V and 3.3V rails without an external regulator — the internal LDO handles the headroom. LVDS output provides a differential signal with typical 350 mV swing into a 100-ohm termination — the controlled impedance trace pair on the PCB must match this differential impedance to avoid reflections at 200 MHz.
Housed in a 6-SMD no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the exposed pad should be soldered to a ground-plane via array for thermal and electrical grounding.
No single-source risk flagged; the MEMS resonator and LVDS output are standard across the DSC1123 family, so a pin-compatible alternate within the same series (e.g., DSC1123CE2-200.0000) shares the same footprint and supply voltage range.
